This study investigated the relationship between perception of an odour when smelled and the taste of a solution to which the odour is added as a flavorant. In Experiment 1 (E1) sweetness, sourness, liking and intensity ratings were obtained for 20 odours. Taste ratings were then obtained for sucrose solutions to which the odours had been added as flavorants. Certain odours were found to enhanc...

Sugars used for sweetening do contribute calories, which can lead to obesity, a risk factor for some chronic diseases. Hence, the craving for sweetness led to discover several forms of alternative sweeteners, which would offer consumers the sweet taste without calories. Stevia rebaudiana Bertoni is a natural herb with low calorie sweetener. Stevioside is one of the principal diterpene glycoside...

The appeal of sweet electronic cigarette flavors makes it important to identify the chemical compounds that contribute to their sweetness. While volatile chemicals that produce sweet aromas have been identified in e-liquids, there are no published reports of sugars or artificial sweeteners in commercial e-liquids. However, the sweetener sucralose is marketed as an e-liquid additive to commercia...

This study was aimed at establishing optimized conditions for hot water extraction of roselle beverage (soborodo) from its calyces as well as the degree of beverage sweetness in the commercial practice. The dried calyces/water ratios involved in the commercial practice ranged between 1:57 and 1:71 (w/v) while the sweetness level of the beverage ranged between 11.2 and 13.3 °Brix. The indices fo...

Neoculin (NCL), a protein with sweetness approximately 500-fold that of sugar, can be utilized as a nonglycemic sweetener. It also has taste-modifying activity to convert sourness to sweetness. NCL is a heterodimer composed of an N-glycosylated acidic subunit (NAS) and a basic subunit (NBS), which are conjugated by disulfide bonds. For the production of recombinant NCL (rNCL) by Aspergillus ory...

Flies have taste cells specifically sensitive to sweetness. It has been suggested that the cells possess two types of receptor sites covering the receptive field of sweetness. By affinity electrophoresis with the site-specific inhibitory polysaccharides, two types of sugar-binding protein were isolated from the labellar extract of the blowfly. These proteins showed consistent sugar-binding spec...

In a previous study we isolated homologues of new oleanane-type triterpene glycosides from leaves of Staurogyne merguensis Kuntze and named them strogins. Strogins themselves have a sweet taste (sweet activity), which diminishes in a few minutes. Subsequent application of cold water to the mouth then elicits a sweet taste (sweetness-inducing activity). In the present study we systematically exa...

The purpose of this study was to evaluate quantitatively the taste of the various total enteral nutrients marketed in Japan using human gustatory sensation tests and an artificial taste sensor. In the human gustatory sensation test, four basic taste intensities (sweetness, saltiness, sourness, and bitterness), as well as 15 kinds of palatability scales, were evaluated according to the semantic ...
